I'm not aware of evidence that biological difference has any effect on someones ability to code?
It's been pointed out to you more than once... It may not have much of an effect on the theoretical ability to code but biological differences sure effect the desire to enter and remain in certain professions. The evidence of such gendered preferences has high degrees of pervasiveness, ubiquity and is demonstrated by groups of very young children and is observed in other primates rendering a claim that it is solely or mainly down to 'societal conditioning' risible. Gendered group differences can also be seen to increase in lots of cases in more egalitarian states with lots of welfare and childcare assistance which is the exact opposite of what the gender ideologues claim should happen but yet is entirely consistent with the hypothesis that the two sexes do make gendered choices, when considered as groups, as when they are more at liberty to choose their own path more stark gender disparities do sometimes appear.
Evidence demonstrating the important points has been posted more than once in this thread so I dont intend to repeat it given I'm on the mobile.
Nothing in this post should be read that I 100‰agree with the google memo or that societal factors have no part to play.
But the presence of gendered preferences for different work is very relevant to Google and any other employers policies with regards to 'equal' opportunities and 'diversity'
Why make a claim that has zero scientific evidence in a critique of your employers policy?
I'm glad we have established your an absoultist ideologue much like your PhD profs argument....
As your quite keen on largely irrelevant jokes and quotes I'll offer you this one
'only a sith deals in absolutes' - Obi Want Kenobi
And why not throw in a second quote whilst we are at it....
'none so blind as those who refuse to see'
Your own graph posted above showing the respective changes in gender distribution is a clear indicator of the stark gender preferences for different sorts of work...
I would be interested to read more about what they classify 'mathematical workers' as because it's a very vague term, more so than any other catergory on that list and I suspect that it may be skewed by less then immediately apparent factors .... for example an increase in female maths teachers... I. E people over things gender preference differentiation
Additionally a lot of the changes on that graph from the 1970's won't reflect solely gender ratio changes in the respective fields as much as changes in the respective fields themselves.....
I. E in 1970 a lot less people would have been involved in 'gender studies' and similar lines of enquiry under the social 'sciences' umbrella and any gender imbalance in these new/increasingly studied and used fields would change the overall gender balance of the wider catergory without necessarily affecting the previous 'core' of work.
It is interesting that 'computer workers' has shown the only signifcant regression on that chart but of all the categories one would observe that 'computer workers' is an almost meaningless term for comparison from 1970 to 2011 as the type of work has changed beyond recognition for 'computer workers' from 1970 to 2011... I would suggest therefore that trying to discern any meaningful trends from that part of the graph is fraught with the possibility for a mass of incorrect assumptions about causal factors....
If I was to rather quickly assess the graph for 'computer workers' I would note that the sharp downturn first occurred between 1990 and 2000....... which is far from a coincidence when even casually considered....
So what happened of relevance to that 1990 to 2000 change?
1) it was a time marked by the start of a mass increase in home computer ownership with a high percentage of homes having at least one PC by 2000
2) it was around the time public access to the Internet first started with massive acceleration in adoption by 2000
And
3) it was around the time the first generation of home computer owning enthusiasts (all those spectrum and commodore owners/ users etc of the late 1970's and 1980's) entered the workforce after school /college/ uni.... (I'm sure I don't need to explain that there was a stark gender dissparity in the numbers of enthusiasts). Before 1990 the people working as 'computer workers' would not, in the main, have grown up as computer enthusiasts as they would not have had access to computers at home or at most levels of study at schools and further education establishments...
Therefore I would hypothesise that the sharp downturn, percentage wise, of women in the 'computer workers' field is not because tech companies suddenly became more hostile to women circa 1990-2000 but because...
1) The nature of the work itself changed....
And 2) It was the first period of time that a personal interest outside of work (home computers) could start to affect who was
interested in entering the field to any significant degree
Alternatively I would like to hear your analysis?
So in summary I find the information you post to support your position to be lacking in any attempt at further interpretation beyond accepting that it must support your, I would say, ideological point of view that gender disparities in tech must be down to the industries themselves and not down to gendered differrences in interests and changes to the actual work being done....
The other comment I would make from your source is that after an initial (proportional) increase of women in Stem till 1990 it looks like the proportion of women in stem has largely followed the percentage of women in the workforce as an overall total... Which is, I would suggest, largely what you would expect and that the heavy pressure to 'get women into stem' for at least the last 20 years has not borne out tangible gains... Because, I would suggest l, people, especially the educated, in places like the US can largely follow their desires and not what some ideologues tells them they should do
